How old were you when you started puberty? Most people will say somewhere between 10-15. There is a smaller percentage of people, though, who will experience those physical and hormonal changes earlier, in some cases MUCH earlier. Ladies, can you imagine starting your period when you were seven years old? Dr. Wendy talks with the endocrinologist who literally wrote the textbook on precocious puberty and a few people who have experienced this rare condition personally or as a parent. Questions?
